今天在使用tcpreplay重放流量时,发现有的数据包没有发送成功:

Warning: Unable to send packet: Error with PF_PACKET send() [215]: Message too long (errno = 90)

从错误提示看出,应该是数据包太大了。我查看了一下发送的数据包:

发现数据包长度已经超过1500(MTU默认为1500),所以问题的解决方法是修改系统的MTU值。

先说一下我的系统环境:ubuntu 12.04

linux系统修改MTU的方法比较简单,一个命令即可:

sudo ifconfig eth0 mtu 3000

这是将网卡eth0的MTU值设置为3000,这样再重新放包,发现数据包被全部发送:
